[0026] like Figure 1-2 As shown, this application provides a high-temperature performance testing device for large workpieces, including a test chamber 1, a heating system, a temperature control system, a dehumidification circulation system, a workpiece placement structure, a grooved track 11, and a control cabinet 2. The test chamber 1 is composed of high-temperature resistant insulation panels. The control cabinet 2 is located outside the test chamber 1. The heating system is located inside the test chamber 1, on the inner walls of both sides of the test chamber 1, and connected to the control cabinet 2. The temperature control system is located inside the test chamber 1 and connected to the control cabinet 2. The dehumidification circulation system is located on the outer wall of the test chamber 1 and connected to the control cabinet 2. The grooved track 11 is located on the bottom plate inside the test chamber 1. The workpiece placement structure is located in the center inside the test chamber 1 and slides on the grooved track 11 via directional wheels 10.

[0027] Specifically, the high-temperature performance testing device for large workpieces provided in this application embodiment achieves accurate testing and analysis of the performance of multiple large workpieces under high-temperature environments through multi-segment independent heating, high-precision time and temperature control, stable support and moving structure, and dehumidification circulation system. The test chamber 1 serves as the carrier for the high-temperature testing environment. It is a rectangular box structure composed of multiple high-temperature resistant insulation panels, used for heating and testing large workpieces inside. The high-temperature resistant insulation panels reduce heat loss during testing. The heating system provides a uniform high-temperature environment, ensuring that the workpieces are heated evenly inside the test chamber 1. The temperature control system precisely controls the ambient temperature, ensuring that temperature fluctuations remain within the required range. The dehumidification circulation system circulates hot air to maintain temperature uniformity within the test chamber 1 and reduces humidity, ensuring environmental stability. The workpiece placement structure supports multiple workpieces for testing. A grooved track 11 is located at the bottom of the test chamber 1. The workpiece placement structure can slide on the grooved track 11 via directional wheels 10, facilitating the transport and placement of multiple workpieces and allowing adjustment of the workpiece heating position. The control cabinet 2 is the central control unit for the entire device, used for controlling various systems and displaying and providing feedback on performance test results.

[0028] Furthermore, the heating system includes a resistance heater 3 and heat-permeable holes 4. The resistance heater 3 is multi-segmented, and these segments are embedded in the heating grooves on both sides of the inner wall of the test chamber 1 in a parallel array. The heat-permeable holes 4 consist of multiple sets of air vents, corresponding to the resistance heater 3 and covering its periphery. The resistance heater 3 is mainly used for heating and raising the temperature, reaching a maximum of 300℃. To ensure sufficient space and aesthetics within the test chamber 1, the resistance heater 3 is embedded in the heating grooves on both sides of the test chamber 1, forming an independent segmented structure evenly distributed in an array on both sides of the inner wall. The heat-permeable holes 4 are elongated air vent structures, corresponding to the resistance heater 3 and completely covering its exterior. This allows the resistance heater 3 to be hidden inside the heating grooves, ensuring both aesthetics and uniform heating of all parts of the workpiece inside the test chamber 1, thus improving testing accuracy.

[0029] Furthermore, the temperature control system includes high-precision thermocouples and temperature sensors, both connected to the control cabinet 2. The high-precision thermocouples and temperature sensors are primarily used to monitor the temperature inside the test chamber 1, enabling precise adjustment of the test environment temperature. During the test, when the temperature inside the test chamber 1 reaches the set temperature, the control cabinet 2 will stop the heating system; the test chamber 1 will continue to maintain its temperature, and when the temperature drops below the set temperature, the heating system will automatically restart.

[0030] Furthermore, the dehumidification circulation system includes a circulating fan 5, a dehumidifying fan 6, and a smoke exhaust fan 7. Multiple circulating fans 5 are provided, all positioned above the outer walls on both sides of the test chamber 1. Two dehumidifying fans 6 are provided, positioned below the outer walls on both sides of the test chamber 1. Two smoke exhaust fans 7 are provided, positioned in front of and behind the top plate of the test chamber 1. The circulating fans 5, dehumidifying fans 6, and smoke exhaust fans 7 are all connected to the control cabinet 2. In this embodiment, eight circulating fans 5 are preferably provided, with four located above the left outer wall and four above the right outer wall of the test chamber 1. During the test, this ensures efficient hot air circulation inside the test chamber 1, guaranteeing uniform internal temperature. Two dehumidifying fans 6 are preferably provided, located below the outer walls on both sides of the test chamber 1. When the ambient humidity is too high, the dehumidifying fans 6 are activated to deliver dried air into the test chamber 1, reducing the ambient humidity and stabilizing the internal test environment. Two exhaust fans 7 are preferably provided, located in front of and behind the top plate of the test chamber 1, respectively. When smoke is generated during the test, the exhaust fans 7 are activated to expel the smoke.

[0031] Furthermore, the workpiece placement structure includes a movable support 8 and a workpiece placement tray 9, wherein: the bottom of the movable support 8 is slidably connected to the grooved track 11 via a directional wheel 10; multiple workpiece placement trays 9 are provided, and the multiple workpiece placement trays 9 are arranged side by side on the movable support 8 from bottom to top.

[0032] Furthermore, each workpiece placement tray 9 has a grid structure.

[0033] Specifically, in this embodiment, the workpiece placement trays 9 are preferably 32, enabling simultaneous high-temperature performance testing of 32 workpieces. The workpieces are placed uniformly on the grid-structured trays, ensuring the stability of large workpieces during testing and preventing displacement or deformation due to thermal expansion. The workpiece placement trays 9 are arranged side-by-side from bottom to top on the movable support 8, depending on the actual situation. The movable support 8 serves two purposes: firstly, to fix and support the workpiece placement trays 9; and secondly, to slide on the grooved track 11 via directional wheels 10, facilitating the transportation and placement of large workpieces and the adjustment of the heating position. Alternatively, the workpiece placement trays 9 and the movable support 8 can be slidably connected. Small directional wheels 10 are configured under each workpiece placement tray 9 to allow for opening and closing of the trays, facilitating the placement of large workpieces.

[0034] Furthermore, control cabinet 2 is equipped with a control system, a display screen, and control buttons. The control system is located inside control cabinet 2 and is connected to the heating system, temperature control system, and dehumidification circulation system. The display screen and control buttons are located outside control cabinet 2 and are both connected to the control system. Control cabinet 2 is the control center of the entire device, possessing high reliability, precise control, and safety protection functions to ensure long-term stable operation and meet high-temperature testing requirements. The control buttons allow users to set the heating time and temperature of the heating system, and to turn the circulating fan 5, dehumidification fan 6, and exhaust fan 7 on or off. The display screen shows the temperature inside the test chamber 1 and various performance parameters of the large workpiece under high temperature conditions.

[0035] Furthermore, control cabinet 2 is equipped with an emergency stop button, which is connected to the control system. During testing, if the temperature becomes too high or an emergency occurs, pressing the emergency stop button will stop the device from working, ensuring testing safety.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
